when I register into your forum, it is a hard work to recognize the characters displayed in code verification section. I have tried several times and it always said code is not correct. Finally I copy the code into windows notepad and solve the problem. Maybe fonts used by internet brownser cause it.

I think some prompts should be added to help people register without difficulty.

I tried it with Western/Eastern European ISO and Windows and it was perfectly legible (not like in your screenshot). Same goes for Unicode. I couldn't try it with Chinese or Japanese due to missing language packs.
